I'm sure all the settings "have been done". Otherwise your server wouldn't be running at all! :) What values are those two settings at? Right now, your error message is saying that the script is no managing to upload more than +-6.5 megabytes... The settings might need to be changed depending on the files you are uploading.

Ahh... yes yes.. Having more than one php.ini file can get confusing :P Note that in my answer I mentioned that you can use phpinfo() to find out exactly which ini file is being loaded.
